in plasma electrons, ions and neutral atoms are all together in an overall neutral mix. so electrons are around, they don't go anywhere

You get the quark-anti quark (meson) and triple quark baryon (or triple antiquark i.e. anti-baryon) bound states (where the quarks/anti-quarks interact with gluons). At a collider experiment, there is no need to "actively cool" the quark gluon plasma, this happens automatically and one sees the hadrons (mesons/baryons/anti-baryons) in the detector. In the ...

The system solves the Euler-Lagrange equations of the Lagrangian: $$L\left(\phi, \frac{d\phi}{dz}\right) = \frac{1}{2}\left(\frac{d\phi}{dz}\right)^2 - 4\pi \int_0^{\phi(z)} \rho(s) ds$$ since the corresponding Lagrange equations are: $$\frac{d^2\phi}{dz^2}= -4\pi \rho(\phi)\:.$$ As the Lagrangian does not explicitly depend on "time" $z$, "energy" is ...
